Answer:
2 moles of ammonium ions required to combine with 1 mole of oxalate ion to form ammonium oxalate.
Explanation:
Ammonium cation=
Oxalate anions =
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound as shown in the image attached.
The ionic compound that formed when ammonium ion and oxalate ions combine is ammonium oxalate.
2 moles of ammonium ions required to combine with 1 mole of oxalate ion to form ammonium oxalate.
Answer : 4.8 florins can you exchange for your 4 guilders.
Solution : Given,
The current exchange rate for every 2.4 florins is 2.0 guilders
As per question,
The exchange rate is 2.0 guilders for every 2.4 florins
The exchange rate is 1 guilders for every florins
The exchange rate is 4 guilders for every florins
Therefore, the 4.8 florins can you exchange for your 4 guilders.
Answer:
See explanation below
Explanation:
You forgot to put the picture to do so. In this case, I manage to find one, and I hope is the one you are looking for. If not, then post it again and I'll gladly help you out again.
According to the picture with the answer, we have a cyclohexane with 4 methyl groups there. Two of them are facing towards the molecule with a darker bond. This means that the alkyl bromide, should have a bromine in one of the bonds, and in order to produce an E2 reaction, this bromine should be facing in the opposite direction of the methyl groups which are facing towards. This is because an E2 reaction occurs with the less steric hindrance in the molecule. If the bromine is in the same direction as the methyl group, it will cause a lot more of work to do a reaction, and therefore, an E2 reaction. I will promote instead a E1 or a sustitution product.
Therefore the alkyl bromide should be like the one in the picture 2.
